Plain rice vinegar is gluten-free — rice is not a gluten grain, and Marukan confirms it.
Yes. Rice vinegar (rice wine vinegar) is fermented from rice — not wheat, barley, or rye — so it’s naturally gluten-free and celiac-safe. Marukan states all its rice vinegars and ponzus are gluten-free (its Genuine Brewed Rice Vinegar is certified GF); Mizkan/Nakano and Kikkoman rice vinegars are also rice-based and gluten-free. Two quick caveats: “seasoned” rice vinegar adds sugar and salt (still typically GF — glance at a ponzu/flavored blend), and never confuse rice vinegar with barley-based malt vinegar.
Plain rice vinegar is gluten-free, and it’s one of the easy ones — it’s simply fermented rice, and rice has never been a gluten grain. It’s the mild, slightly sweet acid behind sushi rice, Asian dressings, and quick pickles, and it’s a celiac-kitchen staple.
There are really only two things to keep straight, and this guide covers both: the “seasoned” versions that add a little sugar and salt, and the all-important difference between rice vinegar (safe) and malt vinegar (barley — not safe). They sound similar; they are not the same.
Why Rice Vinegar Is Gluten-Free
Rice vinegar is made by fermenting rice into alcohol and then into vinegar. Per FDA labeling rules, the gluten-containing grains are wheat, barley, and rye — rice is not on that list. Plain rice vinegar contains no wheat, barley, or rye and is naturally gluten-free; a labeled product meets the FDA under-20-ppm standard.
Brand confirmation backs this up clearly. Marukan states that all of its rice vinegars and ponzus are gluten-free and non-GMO, and its Genuine Brewed Rice Vinegar is certified gluten-free. Mizkan/Nakano and Kikkoman rice vinegars are likewise rice-based and gluten-free — note that Kikkoman rice vinegar is distinct from regular Kikkoman soy sauce, which is wheat-brewed.
Two nuances are worth flagging. “Seasoned” or “sushi” rice vinegar adds sugar and salt — neither is a gluten grain, so it’s still typically gluten-free, but a ponzu or flavored blend can add soy sauce, which is the one place to read the label. And the single biggest confusion is naming: rice vinegar (from rice, gluten-free) is not malt vinegar (from barley, not gluten-free). Never substitute one for the other.
Brand-by-Brand: Which Rice Vinegar Is Gluten-Free?
Plain rice vinegar from any major brand is gluten-free. The only thing to glance at is a seasoned/ponzu blend, and the only thing to never confuse it with is malt vinegar.
| Brand / Product | Made from | Gluten-Free? |
|---|---|---|
| Marukan Rice Vinegar (incl. Genuine Brewed) | Rice | ✓ Yes — brand-confirmed (certified) |
| Mizkan / Nakano Rice Vinegar | Rice | ✓ Yes |
| Kikkoman Rice Vinegar | Rice | ✓ Yes (≠ Kikkoman soy sauce) |
| Store / generic plain rice vinegar | Rice | ✓ Yes |
| Seasoned / “sushi” rice vinegar | Rice + sugar, salt | ✓ Usually GF — verify if soy sauce added |
| Ponzu (citrus-soy rice-vinegar blend) | Rice vinegar + soy/citrus | ~ Marukan ponzu is GF; verify other brands |
| Malt vinegar (do NOT confuse) | Barley | ✗ Not gluten-free |
Cross-Contamination Risk
Manufacturing

Restaurant / Home
Low

- Never confuse it with barley-based malt vinegar.
Rice Vinegar — GF Status
- Marukan rice vinegar (incl. Genuine Brewed, certified GF) — gluten-free

What to Look For — Or Avoid
- Ingredients: rice, water — plain rice vinegar
- A brand-confirmed GF rice vinegar (e.g., Marukan)
- Seasoned rice vinegar with only sugar/salt added
- Confusing rice vinegar with malt vinegar (barley)
- A ponzu/flavored blend with unverified added soy sauce
- Assuming sushi is GF just because the rice vinegar is
Frequently Asked Questions
Rice vinegar is reliably gluten-free, so the questions are mostly about seasoned versions, specific brands, and the malt-vinegar mix-up. Here are clear answers.
Is rice vinegar gluten-free?
Yes. Plain rice vinegar is fermented from rice, which is not a gluten-containing grain. It contains no wheat, barley, or rye and is naturally gluten-free and safe for celiac disease.
Is Marukan rice vinegar gluten-free?
Yes. Marukan states that all of its rice vinegars and ponzus are gluten-free and non-GMO, and its Genuine Brewed Rice Vinegar is certified gluten-free. Mizkan/Nakano and Kikkoman rice vinegars are also rice-based and gluten-free.
Is rice wine vinegar the same as rice vinegar?
Yes, for gluten purposes they are the same product and both are gluten-free. Note that “rice wine” itself (mirin or sake) is a separate product you should check on its own label.
Is seasoned rice vinegar gluten-free?
Typically yes. Seasoned (sushi) rice vinegar adds sugar and salt, which are not gluten grains. It is still usually gluten-free, but a ponzu or flavored blend can add soy sauce — that is the one variant worth a quick label check.
Is rice vinegar the same as malt vinegar?
No — and this is the key distinction. Rice vinegar is from rice and is gluten-free. Malt vinegar is from barley and is not gluten-free. Don’t substitute or confuse the two.
Is sushi rice made with rice vinegar gluten-free?
The rice and rice vinegar are gluten-free. But sushi as a whole can still contain gluten from soy sauce, imitation crab, or tempura — the rice vinegar is not the risk; the other components are.
Can people with celiac disease use rice vinegar?
Yes. Plain rice vinegar is naturally gluten-free and celiac-safe for dressings, marinades, and sushi rice — brands like Marukan confirm it. Just check a “seasoned”/ponzu variety’s label and never substitute malt vinegar.
